Description

  The field of application is a compact and configurable set of golf clubs. The club set of the present invention allows the basic characteristics of the club to be adjusted so that the player can change the length of the shaft, change the head connected to the shaft, and modify the loft angle of the head. By at least one of doing so, the club can be adjusted according to its own stroke. Like any standard club set, the compact set of the invention comprehensively includes shaft, wood, iron and putter.

  In a typical golf club, the head and shaft are fixed. As such, the wide variety of shots required during a game requires a variety of shafts and heads. In golf clubs, the characteristics of the head are determined by the loft angle, which is the angle that the ball strikes, with the loft angle being acute for short and accurate distances and right for longer distances. Like the head, the length and flexibility of the shaft varies with shot distance: a short and stiff shaft for short distances and a longer and more flexible shaft for longer distances.

  Wood and hybrids are designed for tee-off (designated place where the player hits the first shot) or fairway (zone extending from tee to green) stroke. Loft angles usually have a width from 8 ° to 28 °. Depending on the player's style, a set of about 5 heads of this type can be collected in a bag. Wood is classified from No. 1 wood having a loft angle of 8 ° to 13 °, that is, a driver, No. 2 wood having a loft angle of 12 ° to 15 °, and No. 7 wood having a loft angle of 25 ° to 28 °. Wood exists up to 15th wood, but few players use them. Above the second wood is also known as fairway wood. The hybrid is wood-like with a thinner or lower head height and the angle is similar to 5 or 7 wood. Some hybrids have a sharper angle, for example, equal to a 5 iron of about 28 °. The length of No. 1 wood club is in the range of 43-45 inches (109-114 cm), based on average adult height. The length progressively decreases by 0.5 to 1 inch (1.27 to 2.54 cm) as the club count goes up to 7th wood with a length of about 41 inches (104 cm).

  Irons and wedges (irons with very sharp loft angles) are used for medium range and approach shots. In most of these, the loft angle ranges from 15 ° to 62 °, depending on the player's preference, and is prepared by selecting up to about 9 clubs in the bag. There are irons from 1 to 9. No. 1 is equal to a loft angle of 15 ° to 18 °, and gradually increases to No. 9, which is equal to a loft angle of 45 ° to 48 °. Wedges include pitching wedges (47 ° -53 °), gap wedges (50 ° -54 °), sand wedges (54 ° -58 °) and lob wedges (58 ° -62 °). The length of No. 1 iron club is about 40 inches (102 cm) based on average adult height. The length gradually decreases by 0.5 inches (1.27 cm) as the club count increases to a 9 iron of about 36 inches (91 cm). The length of the wedge shaft is about 35 inches (89 cm).

  The putter is used for a green stroke putt to put the ball into the hole. There are various heads with loft angles of 2 ° to 5 °. Players choose the best putter for their competition and put one club of this type in their bag. Although the length varies greatly, the length of most conventional and most used putters is about 35 inches (89 cm).

Golf rules allow up to 14 clubs in a bag.
Other relevant criteria to be considered by the player include shaft weight and dynamic weight or swing weight equal to the concept of moment of inertia in the club. The moment of inertia is determined by the length of the shaft and the head weight.

All of these factors define the range of characteristics that should be considered by the player in selecting the ideal set of clubs, and this concept varies from player to player.
The novelty of the present invention resides in a combination of related functions in golf equipment featuring a compact and reconfigurable format that matches the performance of a standard set of clubs.

  Prior art reconfigurable or adjustable club attempts have not addressed the issue comprehensively, and their technical elements have been in competitions being performed by traditional or standard club sets. The side is not considered.

  The patent and patent application literature addressing the scope of the present invention in whole or in part is extensive. Our prior art review focuses on patents that attempt to comprehensively address the problem, and mechanisms that most closely resemble the present invention.

A problem inherent in the prior patents cited herein is that the proposed design failed to achieve one or more of the following conditions.
a) The length of the shaft cannot be adjusted, and therefore, the number of shafts cannot be reduced, or the length of the shaft is not adjusted to various shot distances (Patent Document 1).
b) Does not provide a suitable head range for most shots. As described above, modern golf requires a series of head types: wood, hybrid, iron, wedge, and putter (Patent Document 1) and (Patent Document 2).
c) It does not provide a head loft angle adjustment mechanism. As a result, a large number of heads must be used, and the advantages of this type of set over the standard set are reduced (Patent Document 3) and (Patent Document 1).
d) Loft angle adjustment mechanism of the head (Patent Document 4), (Patent Document 2) that does not address the sole adjustment necessary to properly lay the head on the ground for various adjusted loft angles .
e) A limited range of adjustment mechanisms that have advantages over conventional sets. These include an adjustable set that requires a large number of components or parts, similar to the conditions of a standard club set (US Pat. No. 6,057,049). Or, conversely, an adjustment mechanism (Patent Document 4), (Patent Document 1), and (Patent Document 2) that reduces the number of components but does not cover the entire range of competition in a standard club set.
f) A linkage or adjustment mechanism that may be at least one of serious failure and misadjustment, and a mechanism that includes a high stress region in the basic design. All wood, hybrid, iron or wedge mechanisms, whether shaft or head, are subject to high dynamic stresses when hitting a shot. In particular, in a compact or small number of sets, material fatigue in high stress regions is definitely increased with repeated strokes, considering that all shots are hit with a small number of club heads. As such, the club and head and associated mechanisms will hit more shots per round than a standard set of clubs. Improper adjustment increases the dynamic load and the possibility of failure of the coupling or adjustment mechanism (Patent Document 3), (Patent Document 4), (Patent Document 1), (Patent Document 2).
g) A construction mechanism that cannot be easily or quickly handled before a shot. An example includes a screw-type shaft-head connector (Patent Document 5).

  Toothed part for setting the loft angle to an individual position that is not necessarily set to the position or angle desired by the player. Furthermore, many such schemes require undue manipulation, requiring a release scheme, a positioning scheme, and a locking scheme (US Pat.

  An important issue to consider, which is the coupling mechanism that prevents the basic design concept from being tightly coupled, is that such coupling is performed by the player on the course before hitting the shot. This results in a coupling mechanism that cannot be adjusted easily and gives a feeling of playing with the parts loosened (Patent Document 3), (Patent Document 4), (Patent Document 1), and (Patent Document 2).

  The basic design concept of the mechanism of the present invention includes at least one of adjustment and coupling that can be performed quickly and provide tolerances between parts based on compression of rigid, basic trigonometric parts. All mechanisms are trying to balance beauty and weight, and avoid high stress areas where parts are affected by premature failure or degradation due to material fatigue.

  Proper adjustment consists of selecting the correct head and loft angle, and the length of the shaft to match the selected head. Such adjustments must be easily made by any player within the allotted time frame before making a shot. The result is a club that is as rigidly assembled as a standard club.

US Pat. No. 4,253,666 US Patent No. 2,091,794 US Pat. No. 6,547,673 US Pat. No. 5,083,779 US Pat. No. 7,207,977

  In a typical golf club, the head and shaft are fixed. As such, the wide range of shots used during competition requires a wide variety of shafts and heads. This forces the player to carry a significant weight and volume club set.

Since the 18-hole course takes place over several hours and over a distance of more than 10 km, carrying a fully equipped golf club requires considerable effort.
This is also a problem when carrying bags in vehicles. The clubhouse helps, but this is still a challenge when playing on two or more golf courses, especially when two or more family members play this sport. Another aspect of the problem is players who are on business trips. Such players only have the option of carrying their own equipment or using rental items. The first option is inconvenient, especially when using an airplane, and the second option can be a less enjoyable experience because the equipment may not fit the player or may have deteriorated due to use. There are many.

  An additional problem arising from the use of typical fixed heads and shafts is that available tools often fall within standard lengths and loft angles. Since the goal of the competition is to round the round with the least possible stroke, it is important how well the equipment can fit the player's stroke, especially the club. However, the player's torso, arm length, etc. are different. Particularly difficult is the case of growing-up children. A significant number of children play this sport, but must play in clubs that do not fit their physique or need to be replaced or modified as they grow up.

  As noted above, prior art attempts with reconfigurable or adjustable clubs have not addressed the problem comprehensively, and their technical elements are performed by traditional or standard club sets. It does not take into account the aspects of competition that are being held. Efforts to partially resolve various adjustment factors have revealed the technical flaws described in the background, and have resulted in most players still prefer a standard club set with a fixed configuration. .

  Proper adjustment consists of selecting the appropriate head and loft angle and shaft length to fit the selected head. Such adjustments should be easily made by any player, whether children, adults or the elderly, within the allotted time frame before making a shot. Finally, the required clubs require a robust adjustment mechanism that is not susceptible to premature breakage or wear. This is particularly important considering that every shot in the competition is shot using one or two clubs.

The novelty of the present invention resides in a combination of related functions in a golf equipment featuring a compact and reconfigurable format that is comparable to the performance of a standard set of clubs.
The first feature is that, like a conventional club set, the compact and reconfigurable set of the present invention includes the 1st to 9th wedges and putters in whole or in part, and the wood driver, fairway It can include wood, hybrids and irons.

  The second function is that each of these head types can change loft angles by mechanism so that the full range of loft angles is adequately covered. This does not prevent the head from extending beyond the loft angle range of the conventional head or defining the head by a more targeted loft angle range. The latter requires a large number of heads in a compact set, but has the advantage that the head behavior closely resembles that of conventional heads, for example, the weight, and thus the moment of inertia or swing weight. The adjustable loft is actuated by a mechanism attached to the back region of the head and connected to a modified hosel. It has a triangular shape and one of its sides can be adjusted manually with a screw.

The second function means that the game can be played with a small number of interchangeable heads, preferably with one or a few shafts.
The above provides the third function of the present invention. Since the proposal is to play using one or a few shafts, these heads and shafts include an exchange mechanism that allows players to assemble the club before the stroke using easily and comfortably . A single shaft is preferred, but a player who wants to use one shaft for wood and another shaft for iron is not limited to including two shafts instead of one in a compact set. In such a case, both shafts include a head exchange mechanism. The head exchange mechanism is composed of a guide pin attached to the hosel, and the hosel is connected to a pair of concentric cylinders at one end of the shaft, and is a ball that locks the mechanism by being housed in the recess of the guide pin. including. The mechanism is operated by the player by moving the outermost cylinder using a finger.

  The fourth feature suggests playing with one or a few shafts, so the length of the shaft needs to be adjustable for each selected head and loft angle. is there. The shaft length adjustment mechanism comprises a shaft with a surface recess that accommodates a sliding handle, the handle similarly accommodating a pair of concentric cylinders at one end of the handle, and It includes a ball that locks the mechanism by being housed in a recess in the shaft. The mechanism is operated by the player moving the outermost cylinder using his finger.

  The fifth function is that the head loft angle changes, so that the head preferably includes a modified sole to ensure that the correct lie (horizontal head is correct for the range of loft angles defined for this head. Is on the ground).

  The sixth function is that any commercially available head with a standard hosel can be used by the head exchange mechanism. This allows the use of a compact set that can be adjusted by a conventional commercial head selected by the player, such as a putter and / or No. 1 wood or driver type head. The hosel is configured to be a socket or neck of a golf club head, into which a shaft is inserted.

The above-described problems are addressed and solved in the present invention and provide advantages. The main ones of these problems are as follows.
Despite significant reductions in volume and weight, the adjustable compact set performs at least as well as a conventional club set.

  A compact set can be used with a commercially available fixed head at the discretion of the player. This is particularly beneficial in the case of No. 1 woodheads and putters, as players tend to stick to specific models, especially with respect to putters.

  The assembly of the adjustable club is simple and can be done in at most 3 steps. The assembling method includes a step a in which a head and a shaft are selected and coupled to each other, a step b in which a loft angle is adjusted and a loft adjustable head is used, and a length c in the shaft is adjusted. These mechanisms are easily operated by the player using his / her finger.

  Once adjusted, the connector is designed to remain firmly connected during the shot, giving the player a solid club and stroke feel.

  With this new equipment, players can adjust the equipment to match their physique and play style during competition, expanding the possibility of more accurate shots. This means that the higher the accuracy, the fewer the number of strokes required to go round, which is one of the important goals in golf competitions.

  The tool also helps polish the golfer's arm to allow for numerous changes for a given shot. The player can select the best combination for accuracy and / or distance, and the equipment remains with the player as the game progresses.

The adjustable set provides a clear advantage for the child. It is because it adapts to a child's physical growth as a tool which can change composition.
The set significantly reduces the volume of a standard club set to 1/5 and the weight to 1/3, respectively, providing the following advantages:

  Players can play rounds with one or two clubs and experience a more enjoyable competition because they do not have to carry heavy and bulky bags over long distances, ie 18 holes, for an average of 10 km for hours .

This is particularly relevant for older players who make up a significant portion of the player population.
An adjustable compact set requires significantly less space and can be easily carried by car or airplane, which is particularly convenient when two or more family members play the sport. Carrying a standard club set to a distant destination is often not feasible due to space or cost issues. The only option is to keep a standard set of clubs on each frequent golf course or rely on rental or rental. These examples do not apply to an adjustable compact set, which, as mentioned above, no longer concerns space or cost issues, so players always have the same equipment everywhere. It retains the significant advantage of being usable.

  The present disclosure should be read based on the detailed description and the drawings briefly described below.

c) means at least one of a fixed loft type comprising the putter head 400, an adjustable loft type, and combinations thereof.

  A compact golf club set that can be reconfigured during competition allows for numerous combinations as determined by manufacturer and player preferences. Examples 1-2 show in detail two possible configurations.

<Example 1>
Example 1 of FIG.
A shaft 100 with an adjustable length;
A replaceable fixed loft 401 putter head 400;
An iron head 300 of an adjustable adjustable loft 302 that can be configured with a loft angle of a sand wedge from 5-9 iron,
Includes a shaft and three heads consisting of an interchangeable wood head 200, which can be a fixed loft angle 201, or an alternative head with an adjustable loft 202 that can be configured with loft angles in the range of 1-7 wood heads A compact set is shown.

  This example shows a very compact four-part set that would be of interest to players who would like to significantly reduce the weight and volume for a standard 14 club set and bag.

  A player who wants to closely match a complete set of 14 clubs may increase the number of elements of his compact, configurable golf club set. Like a pro, players need to select the elements to use in the course. Example 2 covers this case.

<Example 2>
Example 2 in FIG. 2 has two shafts and six heads, a putter head, two iron heads with adjustable loft, a wedge head with adjustable loft, a fixed loft wood driver, and an adjustable loft. A set of 8 parts consisting of a fairway wood. In detail, 8 parts
Adjustable length including a more flexible shaft that allows the replaceable wood head 200 to cover longer distances and a stiffer shaft for the replaceable iron head 300 and replaceable putter head 400 Two shafts 100;
A fixed loft putter head 401;
An iron head 302 with an adjustable loft that can be deployed to cover the average weight and loft angle of the 4th to 6th iron headset 310;
An iron head 302 with adjustable loft that can be deployed to cover the average weight and loft angle of the 7th to 9th iron headset 320;
A loft adjustable iron head 302 that can be deployed to cover the average weight and loft angle of the pitching wedge-lob wedge set 330;
A fixed loft wood head 201 equal to the first wood or driver head 210;
And a wood head 202 with adjustable loft that can be deployed to cover the average weight and loft angle of the 3rd to 7th fairway wood headset 220.

  Weight is an essential part of the head design and construction criteria. The heavier the head, the greater the moment of inertia, that is, the swing weight. Briefly, during competition, one way to change the moment of inertia in the present invention is to replace the shaft head with a head of a different weight. Another way is to change the length of the shaft. The present invention proposes to design a loft-adjustable head with a weight close to the average of the range of heads with lofts to follow.

<Adjustable loft mechanism>
Hereinafter, the replaceable heads 200 and 300 including the adjustable loft mechanisms 500a and 500b will be described. Variations of the preferred loft adjustable iron head 302 are shown in FIGS. A preferred loft adjustable wood head 202 variant is shown in FIGS. 26-30 and a preferred loft adjustable head sole is shown in FIGS. 17-20.

The compact and reconfigurable golf club set of FIGS. 1 and 2 requires interchangeable heads 200, 300 with adjustable loft mechanisms 500a, 500b of FIGS. 21-25 and 26-30, 300 comprises club head faces 506, 506a, 506b and a modified sole geometry 545,

c) The modified sole geometry 545 comprises a scan section 550 defined by at least three sections each including a line 552 along the sole that traverses the volume of the head. Each line is a club head with at least three adjustable loft angles, the head including one intermediate loft angle 547 and two loft angle ends 548 corresponding to the head loft angles in the range corresponding to the adjustable head. It is defined when the surface is in contact with the face 506 and is placed horizontally 551 on the ground 549 in front of the ball. A modified sole geometry 545 is illustrated in FIGS.

  With respect to the head of the adjustable loft mechanism 500 with a standard sole, the steeper loft angles 547, 548, the greater the deviation relative to the horizontal direction 551 defined by the ground 549.

  The modified sole geometry 545 (FIG. 17) allows the head to be supported horizontally on the ground when the loft angle of the head is increased by the adjustable loft mechanism 500. When the sole 504 connects a series of soles (FIGS. 18-20) to a series of loft angles 547, 548 that keep the club head face 506 parallel to the ground 549 in a horizontal direction 551, the modified sole geometry Resulting in a geometric shape 545.

In this case, as shown in FIGS. 26, 29, and 30, the back side head region corresponds to the head sole 504b.

For both configurations, as shown in FIGS. 23 and 28, screws 516a, 516b include concentric connecting dials 519a, 519b that can be rotated by the player with a finger.
For wood head 202 with adjustable loft, dial 519b is above the apex of screw 516b and first apex pivot 511b. As shown in FIGS. 26 and 30, the dial 519b is preferably visible through the outer shell 505b by a perforation 554b in the outer shell.

With regard to any of the above-described preferred embodiment head types as shown in FIGS. 24, 25, 29, and 30, the adjustable loft mechanisms 500a, 500b include three concentric pivot brackets in the loft shaft sections 537a, 537b. The axis of which is parallel to the horizontal line of the head and in the backside head region. The three concentric pivot brackets

At a right angle to the axis of the connected connecting rods 540a, 540b through the loft shaft sections 537a, 537b and through the end fitting the second connecting vertices 512a, 512b. Relative rotation is prevented by a cotter pin including eccentric pins 539a, 539b parallel to the loft shaft sections 537a, 537b, and the guide pins 539a, 539b are connected to the loft shaft sections 537a, 537b and the connecting rods 540a, 540b. Share the radial perimeter of. The guide pins 539a, 539b are confined between the width of the connected connecting rods 540a, 540b and the second apex pivot brackets 530a, 530b. The final method is determined by the profitable manufacturing process, but axial movement can also be prevented by split pins or coherent locks.

  The loft shaft sections 537a and 537b prevent the head from moving in the axial direction by retaining rings 544a and 544b attached to the loft shaft sections 537a and 537b and supported on the inner surfaces of the loft shaft pivot brackets 529a and 529b. The loft shaft sections 537a, 537b also abut the second apex pivot brackets 530a, 530b closest to the toe sides 507a, 507b.

  In a preferred embodiment, the adjustable loft mechanism 500b includes a heel concave surface 553b that partially houses the hosel section 533b in the loft adjustable wood head 202 on the outer surface of the face frame 503b at the heel side 508b. 29, 30, the heel concave surface 553b has the necessary play to allow the hosel section 533 to move, allowing a head loft angle in a range corresponding to the adjustable head.

<Head exchange mechanism>
The head exchange mechanism 170 (FIGS. 10 and 11) includes a pin lock 173, an internal exchange cylinder 177, and an external exchange cylinder 186, all of which slide relative to each other. The internal exchange cylinder 177 houses the pin lock 173. The internal exchange cylinder 177 is connected to the shaft head exchange section 161. The inner exchange cylinder 177 and the outer exchange cylinder 186 can have various concave and convex geometric shapes, such as hexagons.

  The pin lock 173 is permanently attached to the hollow cylindrical projection 198 of a standard hosel 199 and thus connected to the fixed loft heads 201, 301, 401. In other words, the pin lock can be appropriately attached to any commercially available fixed loft angle head, and the commercially available head can be configured as a replaceable head. As shown in FIGS. 14-16, the player selects an existing commercially available fixed loft head 201, 301, 401 with a standard hosel 199 and slides like a standard commercially available shaft. A pin lock 173 attached using an adhesive can be used instead.

  As shown in FIGS. 25 and 30, the pin lock 173 is also permanently attached to the female hosel projections 534a, 534b of the hosel sections 533a, 533b, and is therefore coupled to the heads 202, 302 with adjustable loft. obtain. Optionally, the pin lock 173 may be replaced by male hosel protrusions 535a, 535b that fit into the head change mechanism 170, formed during manufacture of the hosel loft shafts 532a, 532b, and FIGS. Is equivalent to a pinlock male projection 174 raised from a hosel section 533a, 533b or a standard hosel 199 as shown in FIG.

  Pinlock male protrusions 174 raised from hosel sections 533a, 533b or standard hosel 199 have a Torque-resistant geometry. The geometry of the inner surface 178 of the internal exchange cylinder matches the geometry of the outer surface of the pinlock male projection 174.

The internal exchange cylinder 177 houses at least one locking element 183 in the surface radial bore 182.
The pinlock male projection 174 includes on its surface at least one pinlock recess 175 that houses the locking element 183.

  In the coupled position 171 (FIG. 12), the locking element 183 slides radially and is confined to the pin locking recess 175, the radial bore 182 and the inner surface 187 of the outer exchange cylinder.

  In the uncoupled position 172 (FIG. 13), the player slides the outer exchange cylinder 186 and the decoupling recess 188 in the inner surface 187 of the outer exchange cylinder allows the locking element 183 to slide radially and locks. The element 183 is released from the pin lock recess 175.

  The pinlock male projection 174 includes a small diameter end section that is inserted into the internal exchange cylinder 177 and expands into the hosel sections 533a, 533b or a standard hosel 199. The pinlock male projection 174 is a concave or convex polygon, allowing a specific assembly orientation, at least with a unique geometric shape. Pin lock hosel protrusions 176 inserted into hosel sections 533a, 533b or standard hosel 199 allow standard shafts to be attached to hosel sections 533a, 533b or standard hosel 199 in a typical manner. It has a hollow cylindrical geometry with a size.

  The pin lock 173 is used to attach the pin lock hosel protrusion 176 of the pin lock 173 to the hosel sections 533a, 533b or the standard hosel 199 by a method similar to or equivalent to a typical attachment method of attaching a standard shaft. Enabling, these methods include contact cement, cured epoxy resin, locking sleeve, compression cone, coherent lock, expansion joint, axial clamping screw, side clamping screw, bolted or rivet joint, and any Including at least one of its technical equivalents.

  In a preferred configuration, the convex polygonal section that includes the pinlock male projection 174 is defined as a hexagon. At least one hexagonal face has a unique geometric shape, allowing a unique assembly position. The locking element 183 is a ball. One or more locking balls 183 are disposed in one or more conical radial bores 182 provided at equal distances in a region corresponding to the hexagonal section of the inner surface 178 of the internal exchange cylinder. . The pin-locking depressions 175 are concave hemispheres, and the diameter of those concave hemispheres is equal to or smaller than the diameter of the locking ball 183 even at the widest point. When the pin lock recess 175 is disposed in the hexagonal pin lock 173 and the head replacement mechanism 170 is in the connecting position 171, as shown in FIG. 12, the radial bore 182 and eventually the locking ball 183 are positioned. Fits.

  The pin-lock recess 175 alternatively has a configuration that includes a region whose geometry is a rotary circular section, the axis of rotation of the rotary circular section being adapted to the axis of the pin lock and its most The size of the wide section is less than or equal to the size of the locking ball 183.

  The internal exchange cylinder 177 accommodates a coupling spring 184 on the outer surface 179, and the coupling spring pushes the external exchange cylinder 186 into the connection position 171 when extended as shown in FIG. The pressed coupling spring 184 pushes the external exchange cylinder 186 into the unconnected position 172 as shown in FIG. The player's movement with respect to the external exchange cylinder 186 and thus the coupling spring 184 can be axial, torsional, or a combination thereof.

  The head exchange mechanism 170 optionally includes a decoupling spring 185 at the bottom of the internal exchange cylinder 177 that is pressed against the tip of the pin lock male projection 174 at the coupling position 171. (FIG. 12).

  The head exchange mechanism 170 includes a guide pin 181 that moves in the guide slot 180, and can restrict the movement of the external exchange cylinder 186. The guide pin 181 is connected to the external exchange cylinder 186 and passes through the external exchange cylinder 186. The guide slot 180 with the width of the guide pin 181 is a longitudinal recess parallel to the axis and on the outer surface of the internal exchange cylinder 177.

  Regarding the first and second embodiments described above, the pin lock 173 is incorporated into a commercially available fixed loft angle head, that is, a putter head 401 and a first wood or driver head 201. Appropriate pin lock sizes need to be provided so that the size of the interior of a standard hosel 199 varies depending on the type of commercially available head. The options are male hosel projections 535a, 535b, particularly with respect to adjustable loft heads 202, 302 in hosel sections 533a, 533b. The versions of the projections such as the pin lock male projection 174 and the male hosel projections 535a and 535b inserted into the head exchange mechanism 170 always have the same size, and thus the length can be adjusted by the head exchange mechanism 170. Allows the fixed and adjustable loft heads on the shaft 100 to be replaced.

  There is no restriction on the definition of the outer diameter inserted into a standard hosel 199 (FIGS. 14-16). At present, the hosel inner diameter of the fixed loft iron head 301 and the different inner diameter of the fixed loft wood head 201 are common. Both diameters require at least two types of pin locks 173. With respect to the fixed loft putter head 401, there is a broader standard hosel 199 in terms of size and configuration, either male or female. Further, some configurations require a pin lock 173 having an offset. Therefore, a preferred pin lock configuration that fits a commercially available fixed loft putter head 401 needs to be specifically designed for the head. However, such a specific design is only necessary for the pinlock hosel protrusion 176 that is inserted into the standard hosel 199. In a preferred configuration, the size of the pin lock male projection 174 inserted into the head replacement mechanism 170 remains unchanged, allowing head replacement with one or a few shafts 100 of adjustable length.

<Extensible mechanism>
The telescopic mechanism 130 (FIGS. 6 and 7) includes an internal telescopic cylinder 136 and an external telescopic cylinder 133 that slide relative to each other. The internal telescoping cylinder 136 slides over the length adjustable section 163 and is coupled to the handle core 122 and thus to the handle 120. One or more locking radial bores 137 on the surface of the inner telescopic cylinder 136 accommodate at least one locking element 138. The inner telescopic cylinder 136 and the outer telescopic cylinder 133 can have various concave and convex geometric shapes such as hexagons.

  Individual longitudinal positions 165 are formed by at least one shaft recess 165 in the adjustment surface 168. The recess accommodates a locking element 138. The adjustment surface has a torque resistant geometric shape.

  In the locked position 131 (FIG. 8), one or more locking elements 138 slide radially in the locking radial bore 137 and on the inner surface 134 of the outer telescoping cylinder until confined in the shaft recess 165. Move.

  In the unlocked position 132 (FIG. 9), the player slides the external telescopic cylinder 133 so that the unlocking recess 135 on the inner surface 134 of the external telescopic cylinder causes the one or more locking elements 138 to move radially. Allow locking and release the locking element 138 from the shaft recess 165.

  The adjustment surface 168 includes a series of surface shaft depressions 165 made as a continuous surface with respect to the surface of the shaft 160. In other words, the depression is not a hole in the shaft, but prevents the surface material from being interrupted in the middle.

  When the shaft 160 is made of a composite material, the shaft recess 165 of the adjustment surface 168 is such that the entire area around the shaft recess 165 as well as the area including the shaft recess 165 does not interrupt the continuity of the fibers. When the shaft 160 is made of a polycrystalline material such as steel, the entire area around the shaft depression 165 as well as the area containing the shaft depression 165 does not break the continuity of the crystal structure.

  A possible configuration is a shaft 160 of mixed material. The body of the shaft 160 is made of composite material in all sections. However, in order to increase the hardness at the finish of the outer adjustment surface 168, this section is made using a thin sheet of material that is harder than a composite such as steel attached to the inner composite layer. In fact, a preferred configuration has the rigid sheet covering only the outer surface portion including a series of shaft depressions 165 (FIG. 4).

  The adjustment surface 168 includes at least one cut as a guide slot for the telescopic mechanism 130. Such cuts have a torque resistant geometry. In particular, the guide slot may have a U-shape or a V-shape with respect to at least the plane 164 or the shaft surface. The inner surface 139 of the inner telescopic cylinder is adapted to the adjustment surface 168.

  In a preferred configuration, the adjustment surface 168 has a circular section and another section made up of two planes 164 (FIG. 4) facing each other at an angle of 180 °. The plane accommodates the shaft recess 165. The indentation may have the shape of a pair of concave hemispheres arranged in opposing planes and facing at an angle of 180 °. Therefore, the locking element 138 is a sphere whose radius is adapted to the recess.

  In a preferred configuration, the opposing planes 164 (FIG. 4) that house the shaft depressions 165 are made of individual sheets of thin polycrystalline material, such as steel, with their outer surfaces and thus their surface finish layers, And can be attached to the composite of shaft 160. The structure of the sheet of crystalline structural material includes a shaft recess 165.

  The internal telescopic cylinder 136 accommodates a lock spring 142 on its outer surface, and the lock spring pushes the external telescopic cylinder 133 into the lock position 131 when extended (FIG. 8). The pressed lock spring 142 pushes the external telescopic cylinder 133 into the lock release position 132 (FIG. 9). The player's movement with respect to the external telescopic cylinder 133, and thus the spring 142, may be axial movement, twisting, or a combination thereof.

  The internal telescoping cylinder 136 has a positioning radial bore 144 that includes a positioning ball pointer 140 that is partially in the shaft recess 165. The ball is pressed against the shaft in the radial direction by a ring spring 141 that covers the ball 140 and the outer surface of the internal telescopic cylinder 136.

  The internal telescopic cylinder 136 includes a movement stopper 143 for the external telescopic cylinder 133. The stopper is a small tab at the start of the outer surface of the inner telescopic cylinder 136 and fits in the unlocking recess 135 of the inner surface 134 of the outer telescopic cylinder to set a movement limit.

The shaft butt section 166 includes a shaft butt end 167 (FIG. 4) that guides the telescoping handle 110 to limit its maximum length.
<Use of compact and reconfigurable golf club set>
Prior to hitting the shot, the player selects interchangeable heads 200, 300, 400 and shaft 100 with adjustable length. The adjustable shaft 100 is selected when the compact club set includes more than one shaft, as described in Example 2 (FIG. 2). The method of assembling a desired club includes the following steps.

  First step: The player connects the selected interchangeable heads 200, 300, and 400 to the shaft 100 whose length can be adjusted by the head replacement mechanism 170. This may require separating the head previously connected to the selected shaft. The head can be replaced by sliding the external replacement cylinder 186 from the connection position 171 (FIG. 12) to the non-connection position 172 (FIG. 13) by the head replacement mechanism.

  Second Step: With respect to the adjustable heads 202, 302, the player adjusts the loft angles 509a, 509b by turning the dials 519a, 519b on the adjustable loft mechanisms 500a, 500b.

  Third step: The player extends or shortens the shaft 100 whose length can be adjusted by the telescopic mechanism 130 in the telescopic handle 110. The player uses the finger to move the external telescopic cylinder 133 from the lock position 131 (FIG. 8) to the lock release position 132 (FIG. 9). The player slides the handle to the desired position over the length adjustable section 163 and locks the handle to the shaft.

Fourth step: The player confirms the horizontal position of the attached head by placing the sole on the ground in the club configuration and the hitting position in front of the ball.
The order of the second step 2 and the third step is interchangeable.

The following is a detailed discussion of the patent, including a brief description, summary, comparison with the invention, and a review of the invention's conflict and invention level with respect to the patent.

U.S. Pat. No. 7,207,977, “Golf Club Head and Shaft Connector and Method”
The invention disclosed in U.S. Pat. No. 7,207,897 proposes a coupling mechanism that allows the shaft and head to be exchanged. U.S. Pat. No. 7,207,897 discloses a tool that allows head replacement during club construction and a method for assembling the tool. It is not intended for use during competition.

Summary of U.S. Pat. No. 7,207,977 The claims of U.S. Pat. No. 7,207,977 specifically include a connector for use in a club assembly that includes a shaft and a head that includes an adapter, the connector comprising:
A shaft and a first interchangeable connector assembly;
A head assembly comprising a second interchangeable connector, the head assembly sized to be securely coupled to a head adapter. The second connector includes a stop flange that extends radially outward to delimit the head adapter portion.

  A first thread is formed on the first replaceable connector and a second thread is formed on the second replaceable connector, the first and second threads being the shaft and the head assembly. Fit to connect.

US Pat. No. 7,207,897 and comparison of the present invention US Pat. No. 7,207,897 addresses the technical problem limited to a head change mechanism that is operated prior to competition. It is not designed to be used before each shot in the competition.

  In the screw connector, it is difficult to align the axes concentrically. U.S. Pat. No. 7,207,897 creates extreme delays that conflict with USGA Rules 6 and 7 when attempting to connect the equipment during competition.

  In contrast, an important point regarding the connection between the shaft and the head is that the present invention does not use a threaded connector. This is because the play may unintentionally release the head and thus cause a delay.

U.S. Pat. No. 7,207,977 and non-conflict of the present invention U.S. Pat. No. 7,207,897 is a specific solution relating only to shaft and head replacement, so U.S. Pat. No. 7,207,897 is in conflict with the present invention. Not done. For that mechanism, US Pat. No. 7,207,897 uses a solution that uses a threaded connector.

Inventive level of the present invention relative to U.S. Pat. No. 7,207,977 From the elements disclosed in U.S. Pat. No. 7,207,977, the shaft to head disclosed in the present invention, even for those who are knowledgeable I cannot guess the components that work on the connection. The conditions of the present invention are such that they can be exchanged during competition as well as during club construction.

US Pat. No. 6,547,673, “Interchangeable Golf Club Head and Adjustable Handle System”. US Pat. No. 6,547,673, “Interchangeable Golf Club Head and Adjustable Handle System”
U.S. Pat. No. 6,547,673 describes a method for converting a commercially available part into a replaceable golf club system. This system consists of two elements. That is, the first element is intended to be attached to a standard head adapter to replace the standard shaft, and the second element is an insert attached to the bottom of the shaft.

  The head insert and the shaft insert form a quick connector that connects the shaft and the head. Any golf club can be imitated by using different heads that represent the full range of heads of wood, iron and putter types, each with pre-installed head inserts.

  Furthermore, the present invention describes a tool for adjusting the length of the shaft by means of a pin inserted in the upper part of the shaft. The pin cooperates with a plurality of slots arranged in a telescopic sleeve that slides across the shaft.

  While the invention of US Pat. No. 6,547,673 is an attempt to address the technical problems of the present invention, the elements detailed in the present invention significantly reduce the number of heads by allowing variable loft angles. This feature is not included in US Pat. No. 6,547,673.

Summary of US Pat. No. 6,547,673 In US Pat. No. 6,547,673, the attachment means used to obtain a quick connector define an axial slot extending axially along a portion of the head insert. And a circumferential slot extending circumferentially from the axial slot, wherein the shaft insert pin is slid along the axial slot and the shaft insert is rotated to move the pin in the circumferential direction. A head insert is included by additional means defining a circumferential slot in which the head is coupled to the shaft by moving along the slot. The shaft insert for receiving a spring load receiving portion projecting radially outward from the shaft insert, and a spring acting receiving portion for selectively non-rotatingly locking the shaft insert to the head insert; Further comprising means for defining a hole in the head insert.

US Pat. No. 6,547,673 and comparison of the present invention US Pat. No. 6,547,673 is based solely on standard head replacement and shaft length variations, and includes additional loft angle variations, etc. It does not add special features. In order to mimic a conventional 14 club set, the player needs to carry 14 heads in the reduced set. Therefore, only the number of shafts is reduced. Considering a partial reduction, the desired benefits are also partial, and therefore the comparative advantage of this proposal is limited.

  U.S. Pat. No. 6,547,673 claims telescoping adjustments not discussed in detail except what is summarized from the description and the accompanying drawings. The described telescopic mechanism is unsuitable for manufacturing. Slots in telescoping tubular units made from composite materials provide discontinuities in the mechanical properties of the shaft. The interruption of the fibers that support the mechanical loads and high stresses caused by the slot-type geometry increases the loads to an unacceptable level with such materials. The same applies to conventional materials such as steel.

  The shaft does not have a locking mechanism that holds the shaft in a selected longitudinal position, and the way the pin fits into the slot provides little tough connection that the shaft can withstand the impact it receives during competition .

  The quick connector according to US Pat. No. 6,547,673 includes a pin that slides in a slot and is mounted so as not to rotate by a pin that stays in place by a spring or elastic force. Therefore, during competition, there is a risk that a rotational force exceeding the elastic force of the receiving portion is applied to the connector, rotating the mechanism, and concomitantly releasing the head. For this reason, the quick connector according to US Pat. No. 6,547,673 has an operational risk that may cause an accident.

U.S. Pat. No. 6,547,673 and non-conflict of the present invention The present invention and U.S. Pat. No. 6,547,673 disclose distinct features. In US Pat. No. 6,547,673, the telescopic head replacement mechanism is inferior and there is no loft angle mechanism. The present invention is more reliable because it uses a mechanism that more reliably supports the high mechanical loads imposed on mechanical components in golf practice.

The invention level of the present invention relative to US Pat. No. 6,547,673 The present invention discloses additional elements, such as loft angle adjustment, relative to US Pat. No. 6,547,673. The reliability cannot be inferred from the cited prior art.

U.S. Pat. No. 5,083,779, “Universal Golf Club Construction”
The invention disclosed in US Pat. No. 5,083,379 describes the adjustment of shaft length, loft angle, lie angle, weight, and impact surface to produce a variety of golf club configurations.

Summary of U.S. Pat. No. 5,083,779 U.S. Pat.No. 5,083,779 includes a shaft having an upper end and a lower end, an adjustable handle operably associated with the top of the shaft, and a first horizontal axis. A universal golf club having a head rotatably coupled to the element operably attached thereto, the head extending from the body and extending to the first horizontal axis. And a member having an impact surface rotatably coupled to the main body through a second horizontal axis disposed substantially perpendicular to the main body.

Comparison of US Pat. No. 5,083,779 with the present invention US Pat. No. 5,083,779 has a fixed head and therefore cannot adjust the stroke type. For example, a wood head is used for tee off, an iron type head is used for a shot to green, or a putter type head is used for a hole shot.

  By placing a head that is permanently connected to the shaft during competition, US Pat. No. 5,083,797 implies that when the player adjusts the length of the shaft, the lie angle must also be adjusted. doing. Therefore, the shaft adjustment includes two operations. As a result, the adjustment process takes time and contradicts the spirit of the competition, which values the continuity of the stroke.

  The loft angle and lie angle mechanism is based on a toothed coupling. This requires decoupling, adjustment and coupling. In other words, the position is changed by three steps. The time-consuming adjustment process contradicts the principle of stroke continuity in USGA rules 6 and 7.

The toothed scheme has individual positions that do not require setting the position or angle that the player desires to hit a shot.
The shaft adjustment by the pin provides a mechanism that requires tolerances that contradict the sense of proper handling and tight coupling, which gives the player the feeling of a “slack” tool.

Finally, adjusting the weight with the insert behind the head is a time consuming and cumbersome operation that cannot be performed between strokes.
US Pat. No. 5,083,797 and non-conflict of the present invention In conclusion, US Pat. No. 5,083,797 does not consider all the adjustment types described in the present invention and therefore does not conflict with the invention of the present application. . Furthermore, the present invention addresses technical problems by a mechanism that cannot be derived directly from the elements disclosed in US Pat. No. 5,083,797.

Inventive level of the present invention relative to US Pat. No. 5,083,797 In contrast to US Pat. No. 5,083,779, the basic design of the present invention allows free head replacement, long shot with replaceable wood, interchangeable Allows approach shots with irons or hole shots with interchangeable putters.

  In addition, the present invention mimics the competition in traditional clubs with extremely fast adjustments and connections, very tight tolerances to avoid “slack” sensations, and each adjustment position of a compact golf club set. Including a basic design concept mechanism that enables

US Pat. No. 4,253,666, “Personal Golf Set For Par-3 Course”
U.S. Pat. No. 4,253,666 describes a series of three head golf club sets assembled with a single two-section shaft. U.S. Pat. No. 4,253,666 contains a detailed description of a bag for carrying the parts.

Summary of U.S. Pat. No. 4,253,666 This patent relates to means for carrying a club set, in which the attachment means for obtaining a quick connector ensures the hosel, guarantees an axial connection and prevents rotation And a head for use in place of a pin lock with a pair of snap fin springs. The pin lock is inserted into a shaft that includes a slot for insertion of a connecting fin spring and attachment of the head to the shaft.

U.S. Pat. No. 4,253,666 discloses a three head type: an iron type for medium distances, an iron type for short distances, and a putter.
U.S. Pat. No. 4,253,666 also describes a shaft comprising two parts assembled using a variation of the same axial coupling mechanism, the axial coupling mechanism having a fin on one part. Including springs, these fin springs are inserted into slots in the other part of the shaft, thereby rotatably mounting the two shaft parts axially.

Comparison between US Pat. No. 4,253,666 and the present invention US Pat. No. 4,253,666 is based solely on head replacement, which in principle is limited to three heads. Shaft length variation is not proposed, and additional configuration features such as loft angle variation are not added. Given these limitations, U.S. Pat. No. 4,253,666 limits its range to a limited range of strokes. For example, it should be noted that the wood stroke is excluded and is intended for the par 3 course.

  The mechanism consisting of a pair of axially mounted fin springs is not suitable for composite materials because the slots in the tubular unit cause discontinuities in the mechanical properties of the shaft. The fiber interruption that supports the mechanical loads and the high stresses generated by the slot-type geometry increases the loads to a level unacceptable for such materials. This is the same with conventional materials such as steel. This is because the fin spring needs to absorb the significant torque stress generated in the fin base during the impact of the club on the ball, thereby shortening the tool life.

U.S. Pat. No. 4,253,666 is limited in its superiority because it reduces the functionality of a standard club set.
US Pat. No. 4,253,666 and non-conflict of the present invention The present invention and US Pat. No. 4,253,666 describe different features. U.S. Pat. No. 4,253,666 is limited to including three heads, does not propose a shaft length adjustment mechanism, and does not include a head loft angle adjustment mechanism. U.S. Pat. No. 4,253,666 lays the foundation of the coupling mechanism on a fin spring that concentrates stress on the base, thus limiting the type of construction material that can be used and the life of the tool.

The invention level of the present invention relative to US Pat. No. 4,253,666 The present invention discloses additional elements not found in US Pat. No. 4,253,666, such as telescopic shaft adjustment and head loft angle adjustment, They cannot be derived from the cited prior art in terms of implementation and reliability.

The mechanism shown in the present invention is quickly adjusted, easy to operate, and particularly rugged, avoiding the concentration of significant torque stress generated by the stroke.
U.S. Pat. No. 2,091,794, "Golf Club"
U.S. Pat. No. 2,091,794 describes a swivel head connected to an axis containing a gear at its end. A guide pin with a fixed toothed end releases the gear and therefore allows the head angle to be set or adjusted. The guide pin is a part of a screw protruding from the inside of the shaft. Pull the guide pin close to or away from the gear by turning the screw protruding from the shaft. The hollow pin lock houses the mechanism described above.

U.S. Pat. No. 2,091,794 discloses a telescoping adjustment that is operated by a concentric tubular connection between the shaft and the handle.
Summary of U.S. Pat. No. 2,091,794 In the main claim, U.S. Pat. No. 2,091,794 literally includes a head having a hollow stem and a blade and means for pivoting the blade about an axis parallel to the ground. Explains the club. The adjustment includes a circular toothed member rigidly connected to the blade and extending to the hollow shaft, and a shaft having a toothed surface adapted to engage the toothed member and arranged at an angle. A guide pin disposed on the inner side, means for forcibly releasing the guide pin from engagement with the toothed member, and a threaded engagement with the hollow member, And a shaft adapted to engage the guide pin with the toothed member against the forced action of the means when the shaft is screwed into a predetermined distance stem, the means comprising: When the shaft is unscrewed a predetermined distance to allow blade adjustment, the pin is forced to disengage from the toothed member. The head is described as a blade that can strike either face, allowing use with the right or left hand.

  U.S. Pat. No. 2,091,794 describes telescoping adjustments not detailed in the claims, except as outlined in the description and accompanying drawings. The telescoping adjustment is operated by a concentric tubular connection between the shaft and the handle. The shaft has concave recesses in the radial direction at regular intervals. The handle includes a toothed region and at its end includes a lip shaped to be inserted into a recessed recess. The lip is set or released by a female threaded cylindrical part that is screwed into the toothed handle area. To prevent the handle from rotating, the shaft has an axial concave guide slot on its outer surface, while the handle has a concave guide slot on its inner surface.

US Pat. No. 2,091,794 and Comparison of the Invention US Pat. No. 2,091,794 describes loft angle variation in an iron-type head and includes a golf club set including wood, iron, wedge, and putter It tries to imitate the characteristics of all the heads.

  This mechanism does not allow head replacement and limits player shots and possibilities. The present invention allows head replacement, which includes moments of inertia between clubs of different lengths using heads of different weights, proper contact with the ground by a sole designed with the loft angle in mind, and wood And solve the basic problems such as more stable stroke balance by increasing the moment of inertia at the putter head. The present invention allows head replacement, thereby ensuring that the above-mentioned problems are left to the discretion of the player before making a shot.

  The head adjustment mechanism described in U.S. Pat. No. 2,091,794 is complex and therefore prone to failure. The adjustment relies on a toothed area with a very small interference surface. Golf parts are susceptible to significant torque, and when transmitted to small parts, they generate significant stress levels that can break and shorten the life of the tool.

U.S. Pat. No. 2,091,794 describes shaft length variation due to telescoping adjustments based on screwing the part to the end of the handle.
A solution of the same twist setting and untwisting type has also been proposed for head angle adjustment.

  U.S. Pat. No. 2,091,794 adjusts a club before hitting a shot by repetitive actions implied by untwisting and twisting to a desired angle and / or desired length. including. For 72 strokes this is a very cumbersome proposal.

  The mechanism of the present invention is designed to minimize the effects of alignment. Although the loft angle is manipulated by a screw, the screw always sets the loft angle, thereby avoiding all problems of unscrewing and setting.

  In the present invention, the length of the shaft is adjusted by sliding an outer ring located along the handle. The ring sets the position and the length of the shaft by means of a spring, thus minimizing the operation.

U.S. Pat. No. 2,091,794 and non-conflict of the present invention The present invention and U.S. Pat. No. 2,091,794 disclose completely different loft angles and shaft length adjustment mechanisms. The present invention allows head replacement, which is not considered in US Pat. No. 2,091,794.

The invention level of the present invention relative to U.S. Pat.No. 2,091,794 The present invention discloses elements for the same purpose as U.S. Pat.No. 2,911,794, such as telescoping shaft and head loft angle adjustment, etc. The implementation method is different and the reliability is improved. The present invention also incorporates a rapid coupling mechanism that can be used with any standard commercial head.

  The mechanism of the present invention is quickly adjusted, easily operated, and particularly robust, avoiding the concentration of significant torque stress generated by the stroke.
